dbf is an easy-to-use command line tool to show
and convert the content of dBASE III, IV, and 5.0
files, as well as of FoxBase and Visual FoxPro. It
reads xBASE-compatible databases and prints the
content to the screen or converts it to
comma-separated (*.csv) files which can be opened
in Excel, StarOffice, and most other spread
sheets. It can also be used to show some
statistics about the content.

Ctalk adds classes, methods, operator overloading,
inheritance, and complex object expressions to otherwise standard C programs. Programs can use only a few Ctalk objects and methods in an otherwise standard C program, but the language can be used to write entire programs also. Ctalk works on most if not all of the systems that support GCC, the GNU C compiler. The package includes the language, class and run-time libraries, example programs, tutorial, and language reference.

Ctpp is the C99-compatible C preprocessor of the
Ctalk language, which provides object oriented
extensions for C. The preprocessor is compatible with GNU cpp and provides extensions like macro expansion in warning and error messages, saving expanded macros to files, and built-in symbol definition for many command line options. You can download the preprocessor separately while Ctalk is between versions for development.

Red language is a native-code compiled functional, imperative, symbolic, and homoiconic programming language that re-uses most of REBOL's syntax and semantics. Both static and JIT compilation support are planned. A strong emphasis is made on concurrency and both task and data parallelism support using an actor-like abstraction and parallel collections (Scala-like). The target range of usage spreads from low-level system programming (thanks to the built-in Red/System C-level DSL) and embedded systems, up to high-level scripting, with an optional REPL console.

Concordance supports programming Logitech Harmony remote controls from a variety of platforms. This software provides most of the functionality of the Windows software provided by Logitech, but is much smaller and cross-platform.

msmtp is an SMTP client with a sendmail compatible interface. It can be used with Mutt and other MUAs. It forwards messages to an SMTP server which does the delivery. Features include various SMTP AUTH methods, TLS/SSL-encrypted connections (including support for client certificates), support for multiple accounts, DSN, and IPv6 support.

LibDsk is a library that attempts to create uniform functions for accessing floppy drives, raw "dd" disk images, and disk image files in various emulator formats. Its intended use is for emulator authors; it also includes some sample tools to read sectors from discs in CP/M, DOS, and Acorn formats. There is special-case code for direct access to the floppy controller under Linux, and to access the floppy driver under Windows. Java (JNI) bindings are included.

Gforth is a fast and portable implementation of the ANS Forth language. It works nicely with the Emacs editor, offers some nice features such as input completion and history and a powerful locals facility, and it even has (the beginnings of) a manual. Gforth employs traditional implementation techniques: its inner innerpreter is indirect or direct threaded. Gforth runs under Unix, Win95, OS/2, and DOS and should not be hard to port to other systems supported by GCC.

4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a
conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.

DRLX is a DR-DOS application and Linux kernel that loads a
fully functional Linux kernel from DR-DOS. It preserves DR-
DOS in memory and on disk so that when Linux has completed
execution, control is returned to DR-DOS. DRLX allows the
ability to load and run Linux applications from native FAT32 (or
FAT16) filesystems.
